I've been looking for years for a clear video to help explain buffers to students at A level and IB DP level. I've now found it . Brilliant work - thank you

This is so underrated... I totally loved it

Fantastic treatment of a topic that can easily lead to total confusion on behalf of the student; you nailed it though. I watch a LOT of science videos and I'm sure this is the best out of the dozens on buffer solution chemistry that are on YouTube. Oh, and you might get a kick out the fact that you're helping someone 11 time zones from the UK (in Hawaii)....the internet & YT is amazing. Thanks for creating such great content; the prep. work you put in to tightly edit the script really stands out.

Thank you so so much, you have no idea how much this explanation made everything click. Thank you!

The best video on this topic out there

Thank you so so much for this video! You made this topic so much easier to understand.

Those dissociation is based on pH of solvent, they are buffers, that maintain the pH by taking or releasing H+, thereby adjusting pH

Ethanoate ion from CH3COONa can further react with water to form CH3COOH

CH3COO- + H2O ——> CH3COOH + OH-

Does it affect the pH ?

Great video, I'm really grateful 🙏

This is by far the best video about chemistry I've watched so far!!! Very clear, uses simple words, talks slowly and most especially the topic is well tackled TT Hope you guys continue doing videos, will surely support y'all ผ(•̀_•́ผ)

Thank you😅, reading this from libre texts was so confusing

g.p

✨🤍thank you sir... I have a doubt, how do we add hydroxide ions to it? I mean, in which form?
